Wouter Born commented on KARAF-6998:
------------------------------------
I tested integrating Karaf 4.3.1-SNAPSHOT into our openHAB distro and also ran
into configurations continuously being updated without any changes. So I hope
it will be fixed before 4.3.1 is released. We also have .cfg files that are
converted into .json files. I added some debug logging as attachment. If you
want more info I can add it and if there is a fix I am happy to help testing
it! :) I didn't find anything else so far besides this issue. (y)

> Project: Karaf
> Issue Type: Bug
> Components: karaf

> Priority: Major

> Configurations created with configadmin in 4.3 have two issues:
> 1) The configuration is always persisted as JSON by the JsonConfigInstaller
> in 'karaf.etc' and is therefore watched by the file installer. It seems this
> behavior should be governed by the 'felix.cm.dir' setting, which would allow
> these persisted configurations to be placed elsewhere or not at all. This
> differs from the .cfg CM persistence behavior.
> 2) When JsonConfigInstaller examines the configuration and compares it to the
> existing one (setConfig() line 83), by performing a simple .equals() on the
> 'old' and 'properties' hash tables. This does not property handle property
> values that are arrays (valid in OSGi 7). As you know a map simply compares
> the key values using .equals, which for arrays is '=='. This causes the
> configuration to always appear to be modified and the associated component is
> deactivated/activated/modified every 2 seconds.

> Thank you for Karaf and for considering this issue.
